**Explanation**: Cherry-pick of #83792, merged as 450cb14 WASILibc wasn't built for the embedded stdlib in `stdlib/public/Platform/CMakeLists.txt`. New `copy_wasilibc_modulemap_embedded_resource` and `embedded-stdlib-platform-${triple}` targets are added, the latter for `wasm32-unknown-wasip1` only for now. Also added a `wasilibc_functions.swift` test to verify the result. **Scope**: limited to Embedded Swift for Wasm; **Risk**: low due to limited scope; **Testing**: added new lit test to the existing Embedded Swift test suite; **Issue**: rdar://157467412 **Reviewer**: @bnbarham
